For example, the sensors 60 comprise one or more? intensity sensors? light configured to detect the intensity? light radiated by at least one of the lighting fixtures 30 connected to the device 20n. Additionally or alternatively, the sensors 60 comprise one or more? temperature sensors configured to measure an operating temperature of at least one of the lighting fixtures 30 connected to the device 20n. The unit? of measurement processing 253 ? configured to process the measurements M supplied by the sensors 60 and supply them to the controller 251. Preferably, the unit? of measurement processing 253 ? also configured to store in the unit? of memory 255 one or more? M measurements provided by the sensors 60.

In one embodiment, the controller 251 is configured to use the M measurements as parameters in the generation of the SR regulation signal, for example using the M measurements as feedback parameters, in order to guarantee light irradiation at the intensity? desired by the lighting fixtures 30. Additionally or alternatively, the controller 251 ? configured to verify correct operation of the lighting fixtures based on the heat produced during operation.

Preferably, the controller 251 ? configured to detect a deviation of the measurements M supplied by the sensors 60 with respect to a range of expected values, for example stored in the unit? of memory 255. For example, controller 251 ? configured to identify a reduction in the intensity? light radiated by an illuminating body 30 connected to the device 20n with respect to a threshold value and/or a range of intensity values? luminous intensity expected based on the PLED power supplied to the lighting fixture 30 considered ? event indicative of a reduction in the efficiency of the lighting fixture 30 considered. Additionally or alternatively, the controller 251 ? configured to identify an increase or decrease in the operating temperature beyond the lower and upper threshold values, respectively ? events indicative of a malfunction of the lighting fixture 30 considered.

Advantageously, once one of these conditions has been detected, the controller 251 ? configured to generate a warning signal SAV comprising an indication of the deviated measurement with respect to the expected values and, preferably, an identifier of the lighting fixture 30 associated with this deviated measurement. The 251 controller ? then configured to transmit the warning signal SAV to the unit? branch 231 of the interface module 23. The unit? derived from 231 ? configured to transmit the SAV warning signal through the input connector 21 so that the SAV warning signal reaches the main control group 10.

Similarly, controller 251 is preferably configured to generate a report signal SRA periodically or when polled by the main control group 10 ? for example, through a corresponding operating instruction C. Advantageously, this report signal SRA comprising one or more? operating data of the device 20n and/or of the lighting fixtures 30 connected to the device 20n. For example, the 251 controller ? configured to generate a report signal SRA comprising a sequence of measurements M performed, operating instructions C or alternate operating instructions D performed, and/or power values PLED ? and/or VLED voltage and ILED current values? delivered in a predetermined time interval, for example corresponding to a period between a transmission of the SRA report signal and the next SRA or a period of time preceding an interrogation performed by the main control group 10.

The warning signal SAV and/or the ratio signal SRA are analyzed by the main control unit 10, to monitor the operation of the devices 201-20N of the system 1 and the lighting fixtures 30 connected thereto. In particular, the warning signal SAV and/or the ratio signal SRA make it possible to determine in a centralized way the correct operation of the system 1 and make it possible to precisely identify lighting fixtures 30 or devices 201-20N which require maintenance or replacement.

? however it is clear that the examples reported above must not be interpreted in a limiting sense and the invention thus? conceived ? susceptible to numerous modifications and variations.

For example, the system's master control group can understand more ethernet output lines each adapted to supply a power signal SA and a data signal SD to a respective sequence of power and regulation devices, and the one or more lighting fixtures controlled by them.

In an alternative embodiment (not shown), the units? of the control module are to be integrated into a single unit?, for example as a system on chip (SoC). Similarly, even the units? of the interface module can be integrated into a single unit?.

In one embodiment, the operating instructions contained in the data signal SD, transmitted by the main control unit, are used by the controller to select one or more? command sequences stored in the control module memory. In this way, ? It is possible to reduce the volume of data transmitted in the system.

In alternative embodiments, one or more? devices can be connected ? in addition or as an alternative to the sensors mentioned above ? to one or more sensors selected from: a presence sensor, an audio sensor, a heat sensor and a smoke sensor. This sensor? associated with the luminaire or with an environment in which ? installed the luminaire connected to at least one output terminal.

For example, a timed procedure can? provide for the activation of one or more? of lighting fixtures coupled to a device when a presence sensor detects the presence of an individual in the installation environment of the lighting fixtures. Similarly, an emergency procedure can provide that one or more of the lighting fixtures coupled to a device are turned on at maximum brightness? obtainable to ensure the best visibility? possible in emergency conditions, when the sensors provide a measurement above a threshold value or outside a range of expected values. Advantageously, the control module of the device can? be configured to automatically manage the start of timed and/or emergency procedures, ensuring greater responsiveness? and reliability? of the system to predetermined situations, especially emergencies.

Naturally, all the details can be replaced by other technically equivalent elements.
